Methadastrol/PCT ArimeDexin Good/ Bad

I am starting a cycle of Meth... by performance anabolics, and I am wondering if I take ArimeDexin by performance anabolics is the proper thing to do? The product states there is no estrogen conversion? I am going to take a natural test booster mid way through the cycle, but I am still wondering if I should take the PCT? Will it hurt me and make my Bodies levels go wack like a PH?
Thanks
